The company claims that TETRA-G removes traditional scalability and cost barriers to TETRA deployment for customers deploying either single site or multisite digital radio systems. It features integrated connectivity with land-line telephony and IP network traffic, giving maximum operational flexibility.

The first TETRA-G solution, the TETRA-G Base Station, is the World's first truly scalable single-carrier TETRA solution with integral PBX teleconnect as standard. The Base Station can expand seamlessly from a single base station to a national network.

According to Team Simoco, until now it has not been cost-effective to add PBX connectivity to traditional single-carrier TETRA solutions because the costs of the required switch card are prohibitive. Furthemore, expanding beyond a single-site deployment can often mean the original hardware is rendered obsolete.

The new single-carrier TETRA-G Base Station provides a control channel and three traffic channels, and is supplied complete with a basic rate ISDN telephone interface supporting 2 concurrent telephone-to-radio calls, which can be routed via IP. The Base Station can easily be expanded as more channels are required, to support multiple carriers through the addition of further TETRA-G units.

Team Simoco managing director Mike Norfield said: "This is a key development in the digital radio market. By integrating PBX connectivity and switching into a base station unit, TETRA-G enables easy and progressive expansion from ruggedised, single-site solutions to country-wide deployments while safeguarding customers' investments at every step. It further underlines the progress we are making in developing radio communications systems that deliver total flexibility and real price / performance benefits to users."

TETRA-G system management is through a Windows XP programming package, providing a range of reporting and control options including call logging, fast database downloads and online or offline configuration changes.

The introduction of TETRA-G follows the 2005 launch of Team Simoco's Xfin technology, which converges professional radio and IP-based voice and datacomms. With Xfin, Team Simoco won the Federation of Communications Services (FCS) 2005 Gerald David OBE Award for innovation in business radio.

TETRA-G and Xfin make Team Simoco the leader in analogue and digital radio solutions which allow seamless, fully scalable expansion from one base station to complete multisite systems.

Further TETRA-G solutions will be announced through 2006 and into 2007.
